To aZZ'whmnz'tma concern. i "-i Be it known t at I, Jorm R, Kpivz mm, a citizen of the United" States, and a resident of Gordon, in the eountyofDoug Ins and State of Wisconsin, have invented.

a new. and Improved Insect-Escape for Screens, of which the following is a. full, clear, and exact descriptionp' i I The invention relates to screen's, articularly door and window screens, and as for an object to rovide an escape screen whereby flies or t e like can find exit from a chamber and are prevented from enteringthe chamber from the outside.

For the purpose mentioned use is made of a screen provided with apertures and a closure mounted on theframe of the screen to close the said apertures with'means for normally holding the closure away from the apertures.

Reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corres onding parts in all the views, and in whicli- Figure 1 is a fragmentary side elevation of a screen equipped with my device, arts being broken away to disclose the un erlying structure; Fig. .2 is a sectional view on the line 2-2 in Fig. 1, and showing the closure in normal position; Fig. 3 is a similar view but showing the closure disposed to close the apertures in thescreen; and

Fig. 4 is a perspective -view disclosing a.

portion of the apertured screen. Referring more particularly to thedrawlugs I provide a screen 10 secured to a frame 11 constituting a part of the screen,

and formed in the screen 10 are a plurality of apertures 12, with strips of wood 13, se-

cured to the frame 11 on both sides of the apertures. A closure member 14 is hingedly mounted to depend from tlle frume 11 and a spring catch 15 provided with a right angled holding end 16 is secured to the frame 11 andiadapited to normally on go the closure 14 to hold the some awn m the apertures 12 as will be seen in F lg. 2.

lVhen there are. flies or insects on the innor side of the screen, the closure 14 is secured by the catch 15 as shown and as inany "insects from 'entering a sects naturally moietbward the upper end of a screcn,'they soon find exit through the apertures 12. If it is desired to revent number through the apertures 12 in the screen, the closure 14 is released from the catch 15,

'nnd gravitationally assumes a' position to close the apertures as will be seen in Fig. 3, thus preventing the insects from entering through the said apertures.

From the foregoing description it will he seen that a substantial and efiicicnt escape for insects is provided and the same is also adopted to prevent the insects from outerin a room or chamber through the screen.

div painting the closure a bright color on the lower side thereof, it would serve as an attraction for flies orinsocts, and although for the purpose of describing my insect escape for screens, I have shown a particular construction, it will be understood that the scope of the invention is defined in the appended claim.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

In a device of the class describcdm frame, a screen secured to the frame, strips extending across the frame and secured to the ends thereof, the said strips being on one side of the screen, a plurality of apertures within the screen and between he said strips, a closure member hinged on the said frame, the screen being positioned between the strips and the closure member, the said member in normal osition lying closely adjacent the said strips whereby the openings in the screen are covered,aspriugcatch carried by the said frame and remote from the said closure member whereby the said member may be moved on its hinges to uncover the openings in the screen and may be held in such position by engagement with the spring catch.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
